IMPROVEMENT IN MACHINES FOR SWEEPING AND CLEANING STREETS.

Specification forming part of Letters Patent No. 3,203, dated July 28, 1843.

To all whom it may concern:

Be it known that I, ALEXANDER J ONES, of the city of New York, in the State of New York, have made certain new and useful Imrovements in the Manner of Constructing a j Iachine for Cleaning the Streets of Towns and Cities and I do hereby declare that the following is a full and exact description thereof. 7

In the accompanying drawings, Figure l is a side elevation of my machine, and Fig. 2 a plan thereof.

'VV W W W aretwo wheels, which run on the ground in the manner of ordinary cart wheels.

AA is the hub of one of these wheels, which wheels run on axles or gudgeons. a a, that pass through E F, which constitute the side timbers and shafts of the machine, and through the beams or levers T T, which vibrate on the said axles and carry the brushwheel Q Q at their rear end. This brushwheel mayrbe raised or forced downat pleasure by the driver of the machine.

O0 is an endless apron of leather, satn- 7 rated cloth, or slats of wood,or of metal, properly jointed together. The endless apron O 0 runs on two rollers, which cross the machine at N and N. The roller N is driven by means of a whirl R and bandb b, which band receives its motion. from the hub A A of the Wheel W, around which it passes.

To drive the revolving brushes Q Q, a

crossed band C 0 passes round a pulley Y on the shaft X X of the brush-wheel and round a puliey'P P, the shaft of which is sustained by uprights Z, mortised into the levers orbeams T T. The pulley P P is driven by means of a band passing around a pulley V, made fast tothe wheel IV", and passing around apnlley Son the same shaft D D with the pulley P P. A shoe E, consisting of a concave piece of sheet metal, rests upon the ground at the rear of the machine and works on gudgeons at each of its ends at the lower parts of the uprights F, making a part of the frame of the machine. The upper part of this shoe rises above the upper side of the endless apron O O, and serves effectually to enable the brush-wheel to deliver the whole of the dirt onto the endless apron. I connect the shoe E and the rear, end of the levers T together by means of a link or chain, as

shown at e e, so that when the revolving brush is raised the shoe also willbe raised with. itclear of the ground and admit of the unobstructed turning or backing of the machine; Y

B is'a box or receptacle near the fore part of the machine, into which the dirt is delivered by the endless apron O'. This box is to be so attached as that itcan be liberated, 4

hauled off, and another supplied at any moment.

' It is necessary to-have the revolving brushwheel completely under control, so that it may be borne down onto the ground with any desired degree-of force, which will vary considerably with the nature of the dirt to be removed and the state of the weather.- As

in as new, and desire to secure by Letters- Patent, is-

The manner in which I have arranged the revolving brush-wheel so as to turn on the rear ends of the vibrating arms or levers T T, that have their fulcrum on the main axle of the cart-wheels, in combination with the shoe and endless apron attached to the main or cart frame, the shoe being suspended by a chain or cord to the arms T T, by which arrangement the brush and shoe may be lifted up from the street and by the flexibility of the chain the brush may be made to bear with any degree of pressure upon the shoe.

I do not claim the brush, shoe, and endless apron independently of this particular arrangement.

I do not intend tolimit myself to any particular material for forming the revolving brushes, as thesemay be made of splints of any suitable kind of wood, of whalebone, or

of otherelastic material. The splints or of bristles in those brushes where they are fibers may be firmly confined betweenbars of secured by Wires.

metal by intervening rods of iron, the Whole 7 being confined by means bf screw-bolts, and ALEXANDER JONES it Will be found advantageous to have the Witnesses:

fibers of double the required length, so that WILLIAM V. MILNOR,

they may be folded together in the manner SAMUEL E. GILES.
